Cytoarchitectonic organization of the entorhinal cortex of the canine brain

The entorhinal cortex of the Megachiroptera: a comparative study of Wahlberg’s epauletted fruit bat and the straw-coloured fruit bat

“…The distribution of zinc-containing boutons in bats is comparable to observations made in the guinea pig, dog, and pig (Geneser-Jensen et al 1974;Holm and Geneser 1989;Wóznicka et al 2006). In the rat and mouse, the staining is moderate in layers Ib and II of MEA and increases gradually across layer III to become very intense at the layer III/IV boundary (Slomianka 1992;Slomianka and Geneser 1991).…”

“…The lateral fields, DIE and DLE, extend rostro-caudally but in bats, as in primates, the corresponding fields, E L and E R , extend mediolaterally, obliquely to the rhinal sulcus. Although functional specialisations of the EC necessarily will result in differences in the detailed structure of subfields between species or larger phylogenetic groups, which have justified species-specific nomenclatures (e.g., guineapig: (Uva et al 2004); dog: (Wóznicka et al 2006)), we do not believe that this is a productive approach in the long-term for a cortical region that most likely shares basal functional aspects in all mammals.…”

“…Cytoarchitectonic descriptions of the MEA in the rat (Insausti et al 1997), mouse (Slomianka and Geneser 1991), dog (Wóznicka et al 2006), macaque (Amaral et al 1987), baboon (Blaizot et al 2004) and human (Insausti et al 1995) indicate the stellate cell is the dominant neuronal phenotype. Quantitative studies estimated that stellate cells constitute 67-81% of the neuronal population and pyramidal cells between 16-32% in the rat and human MEA layer II (Mikkonen et al 2000;Schwartz and Coleman 1981).…”

Cytoarchitecture and myeloarchitecture of the entorhinal cortex of the common marmoset monkey (Callithrix jacchus)

“…In our preparations, we did not subdivide the deep layers because the lamination pattern was not evident. In dogs (Woźnicka et al, ), the deep layers are poorly developed, and not sublaminated. In marmosets, the labeled cells were distributed along most of the rostrocaudal extent in the deep Layers V and VI after retrograde deposits were observed in the caudomedial subdivision of the auditory belt area (de la Mothe, Blumell, Kajikawa, & Hackett, ), and the cells in Layers III, V, and VI project to the caudal CA1 area of the hippocampus (Schwerdtfeger, ).…”

The size of non-hippocampal brain regions varies by season and sex in Richardson’s ground squirrel

“…The rat atlas was occasionally supplemented by the mouse (Franklin and Paxinos, 2008) and the marmoset (Callithrix jacchus; Hardman and Ashwell, 2012) brain atlases. Supplementary material was also used to aid in border definition for the mPFC (Heidbreder and Groenewegen, 2003;Markham et al, 2007), EC (Burwell, 2001;van Groen, 2001;Uva et al, 2004;Woznicka et al, 2006) and SC (Major et al, 2000;Baldwin et al, 2011;Fredes et al, 2012). Because it was difficult to precisely define the dorso-ventral borders of the CC for coronal sections, the internal capsule was included in all CC volumes.…”
